If you cough, wheeze or feel out of breath during or after exercise, it may be more than exertion causing your symptoms. You might have exercise-induced asthma. As with asthma triggered by other things, exercise-induced asthma symptoms occur when your airways tighten and produce extra mucus.

If you have exercise-induced asthma — also called exercise-induced bronchospasm (BRONG-ko-spaz-um) — physical exertion may be the only thing that triggers your symptoms. Or, exercise may be just one of several things that trigger your asthma. But having exercise-induced asthma doesn't mean you shouldn't exercise. Proper treatment and precautions can keep you active — whether you're strolling through the park or competing for Olympic gold.
